I'm 5w3 days today and I just got back from my first OB appointment. He did a transvaginal U/S and was able to see/measure the sack. It was measuring perfectly. There was obviously no heartbeat yet as it was too early but I was wondering what the earliest was that you were able to see/hear the heartbeat? I have another appt in 2 weeks and I'm really hoping it shows up then! Thanks
